Title: Semiconductor laser device
Inventor: KUME MASAHIRO
IPC: H01S5/223
Filed: 1984-06-12
Abstract: PURPOSE:To obtain a device which is able to keep both of return light induced noises and astigmatic differences practically permissible level, by a method wherein a double hetero structure is made on a base plate having a specified step, and a wave guide structure in the lateral direction is made to have the character of the gain wave guide type besides the perfect refractive index wave guide type, and the wave guide structure is made intermediate of the two structures. CONSTITUTION:A step of the height of 1.9+ or -0.2mum is formed on an n type (100) GaAs base plate in the <0-1-1> direction, and a double-hetero structure is formed on the base plate having this step by the liquid phase epitaxial growth. In this case, a Ga1-xAlxAs active layer 10 (x-0.07) which is inserted between an n type Ga1-yAlyAs clad layer 9 and a p type Ga1-yAly As clad layer (y-0.35), is bent at the step part of the base plate, and since the liquid phase grow speed at the step part is a little faster than that of the flat part, the film width becomes larger than that of the flat part. Accordingly, the active layer obtains the effective refractive index difference at the step part in the lateral direction, and the wave guide structure becomes the refractive index wave guide type. Hereby, the gain wave guide character can be added to the wave guide structure, and an intermediate condition of the wave guide structure is realized by refractive index and gain, and the returnlight induced noises are few than that of the pure refractive index wave guide type, and the astigmatic difference can be made small than that of the pure gain wave guide type.

Title: Data transmission system
Inventor: SHIMIZU RYOTA
IPC: H04B3/46
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent control due to errors in data in advance by detecting a fault in mutual controllers only through a transmission line, without the use of an exclusive cable through which occurrence of a fault of the controller is delivered. SOLUTION: In a data transmission system, where one controller 1 and other controller 2 interconnected by a transmission line 3 transmit data with each other, the one controller transmits quality data '0', '1' cyclically (4) to the other controller, the other controller transmits the quality data via an inverting means 8 that confirms soundness of the other controller, logic means 6, 7 process the transmitted quality data and the returned quality data so as to detect normality and abnormity of the controllers or the transmission line. In this case, only when the respective controllers or the transmission line is normal, are the quality data updated (5). Furthermore, time limit operating means 9, 10 provided in the other controller discriminate the quality data to be in error, when the quality data are not replaced cyclicly over a prescribed time.

Title: Production of expanded confectionery
Inventor: OZAKI TAMIO
IPC: A23G3/00
Filed: 1986-05-23
Abstract: PURPOSE:To form an uniformly expanded structure, by carrying out operation of heating and compressing, keeping the distance between the top and bottom forces as it is, releasing only the compressive force, continuing heating in this state, expanding a confectionery material and removing steam in the heating after compressing. CONSTITUTION:A confectionery material 6, e.g. polished glutinous rice, etc., is put in a middle force 1 and top and bottom forces 2 and 3 to carry out heating from the start of production to the end thereof. A given time from the start of production is a process for steaming and kneading the glutinous rice. After passing through this process, the top force 2 is lowered to produce and form a rice cake. The position of the top force 2 is kept as it is and the presence applied to the top force 2 is reduced to zero to apply only the weight of the top force 2 to the glutinous rice. Heating is continued in this state to carry out expanding and drying and the surface is roasted to beautiful brown and colored. Steam generated from the confectionery material 6 from the start to end of production is released from a clearance 4 to the outside. As a result, the expanded tissue becomes uniform and fine texture and a product having both a good taste, e.g. crispiness, etc., and an uniform thickness and whole shape can be produced.

IPC: G01S13/70
Filed: 1989-05-12
Abstract: PURPOSE:To enhance distance measuring accuracy by calculating the distance of a target on the basis of one transmission signal and, at this time, judging the presence of a target at a distance 1/2 the aforementioned distance on the basis of the transmission signal related to a gradient modulating signal. CONSTITUTION:When the judging signal of an added control discriminator 38 is one showing that a target 14 is not detected at the distance corresponding to a rising time T/2, a validity judging circuit 44 applies a connection order connecting a tracking discriminator 26, a modulator 10 and an added modulator 32 to a signal change-over device 24. Even when an object looking like the target is detected at a certain distance, by detecting the distance 1/2 said distance, it is judged whether said object is a false target present at a distance twice an actual distance due to the multiple reflection of the radio wave emitted from a transmitting-receiving antenna and only the target 14 is tracked and an accurate distance can be measured.
